Abstract
Einkaufstrolley mit einer motorischen Treppensteighilfe mit motorisch angetriebenen rotierbaren Hebelarmen (7), mit einer Ladefläche (15), zwei angetriebenen auf je einer Radnabe (1) angeordneten Radreifen (13) und einem motorischen Antrieb für eine translatorische Bewegung des Einkaufstrolleys, wobei der motorische Antrieb über Antriebskomponenten mit den Radreifen (13) abkoppelbar verbunden ist, wobei • die Radnabe (1) feststehend ist und die Radreifen (13) rotierbar auf der Radnabe (1) angeordnet sind, • die Antriebskomponenten zumindest teilweise in der Radnabe (1) aufgenommen sind, und • die Antriebskomponenten ein Reibrad (17) aufweisen und eine Hebelmechanik (16) zum Ankoppeln des Reibrads (17) an den Radreifen (13) vorgesehen ist.Shopping trolley with a motorized stair climbing aid with motor-driven rotatable lever arms (7), with a loading surface (15), two driven on each wheel hub (1) arranged wheel tire (13) and a motor drive for a translational movement of the shopping trolley, wherein the motor drive via drive components to the wheel tires (13) is detachably connected, wherein • the wheel hub (1) is fixed and the wheel tires (13) are rotatably mounted on the wheel hub (1), • the drive components are at least partially received in the wheel hub (1) , and • the drive components comprise a friction wheel (17) and a lever mechanism (16) for coupling the friction wheel (17) to the wheel tire (13) is provided.
Description
Die Erfindung betrifft einen Einkaufstrolley.The invention relates to a shopping trolley.
Stand der Technik ist die Bewegung des Trolleys rein mit Muskelkraft, was bei älteren Menschen zu Problemen und Gefährdungen führen kann. Stand der Technik sind auch solche Trolleys, die mit motorischem Antrieb unterstützt werden, deren Handhabung aber kompliziert ist und deren mechanischer Aufbau in der Herstellung kostenintensiv ist. Zudem können manche der bekannten motorisch betriebenen Trolleys nur motorisch betrieben werden. Bei technischem Ausfall des motorischen Antriebs muss für die Bewegung des Trolleys die gesamte Reibungskraft der Antriebskomponenten mit überwunden werden. Zum Stand der Technik wird beispielhaft auf die Druckschriften

Die
Der Erfindung liegt die Aufgabe zugrunde, einen in der Handhabung unkomplizierteren und kostengünstigeren Einkaufstrolley mit einer Treppensteighilfe vorzuschlagen.The invention has for its object to propose a more uncomplicated in handling and less expensive shopping trolley with a stair climbing.
Diese Aufgabe wird mit einem Einkaufstrolley gemäß dem Hauptanspruch gelöst. Weitere vorteilhafte Ausgestaltungen sind den rückbezogenen Unteransprüchen zu entnehmen.This object is achieved with a shopping trolley according to the main claim. Further advantageous embodiments can be found in the dependent claims.
Die hier vorgeschlagene Lösung des Problems soll die Außenmaße manuell betriebener Trolleys nicht übersteigen, einfachst zu bedienen sein, wenige Komponenten und wenig Eigengewicht aufweisen. Zudem soll der motorische Antrieb abkuppelbar sein, so dass bei nichtmotorischem Betrieb keine Reibungskräfte des Antriebs mit überwunden werden müssen.The proposed solution to the problem should not exceed the external dimensions of manually operated trolleys, be extremely easy to use, have few components and low weight. In addition, the motor drive should be uncoupled, so that in non-motor operation no frictional forces of the drive must be overcome with.
Die hier vorgeschlagene Lösung sieht eine Integration der Antriebskomponenten in die Radnaben der beiden Räder vor, wobei die translatorische Bewegung des Einkaufstrolleys durch die Rotation der Radreifen um das Zentrum der feststehenden Naben und die Treppensteigfunktion durch einen Hebelarm, dessen Rotationszentrum radial zum Zentrum der Nabe versetzt ist und durch diese hindurch verläuft, bewerkstelligt wird. Des Weiteren wird eine Abkoppelung der Antriebskomponenten vom Radreifen vorgesehen, sobald die elektrische Versorgung der Antriebskomponenten unterbrochen wird. Des Weiteren wird vorgeschlagen, zwei Detektionsleisten zur Erkennung von Hindernissen wie z. B. Treppen in den Korpus des Trolleys zu integrieren, welche beim Auflaufen auf Hindernisse einen elektrischen Kontakt herstellen, wodurch der Antrieb für die Treppensteighilfe aktiviert wird und gleichzeitig die Antriebsmotoren für die translatorische Bewegung deaktiviert werden.The solution proposed here provides for an integration of the drive components in the hubs of the two wheels, the translational movement of the shopping trolley being offset by the rotation of the wheel tires about the center of the fixed hubs and the stair climbing function by a lever arm whose center of rotation is radially offset to the center of the hub and passes through them, is accomplished. Furthermore, a decoupling of the drive components is provided by the tire as soon as the electrical supply to the drive components is interrupted. Furthermore, it is proposed that two detection bars for detecting obstacles such. B. to integrate stairs in the body of the trolley, which establish an electrical contact when it hits obstacles, whereby the drive for the stair climbing aid is activated and at the same time the drive motors are disabled for the translational movement.
